ABSTRACT
This study considered the mineralogical, elemental composition in form oxides and engineering properties such as particle size, specific gravity, bulk density; water content and atterberg limits of two kaolin deposits in Kpankorogi in Edu Local Government of Kwara State and in Ijero-Ekiti in Ijero-Ekiti Local Government Area, Ekiti State.This is with a view to assessing their potentials for Various industrial applications. The analyses includes X-Ray Diffraction (XRD and X-Ray Fluorescence(XRF). It was observed that the kaolin sample from Kpankorogi is dominated by Quartz and the one from Ijero- ekiti by Orthoclase. The result of the chemical analysis indicates the presences of SiO2, Al2O3, Fe2O¬3, TiO2, MnO, CaO, MgO, K2O, Na2O, CuO, ZmO, Cr2O5, V2O5 and Sc2O3. The X RD In particular, shows that Kpankorogi kaolin contains Quartz and Kaolinite while Ijero- Ekiti contains in addition to kaolinite,s orthoclase and Muscovite. Considering the possible applications of the two kaolin deposits, it was observed they do not meet the required standards completely in all instances.

CHAPTER TWO - [ Total Page(s): 2 ]Kaolin also finds application as crystal to promote organic reactions, such as petroleum cracking or de-polymerization of large organic molecules found in natural hydrocarbons as demonstrated by (Iglewe and Nwokolo, 2005).The grain size and shape of kaolin is used to advantages in the paper industry, where it is used both as a filling agent and as coating agent also printing inks tend to adhere better to kaolin –treated paper surface (Velde, 1992, Aliyu, 1996). Both grain and sha ... Continue reading---
CHAPTER THREE - [ Total Page(s): 6 ]CHAPTER THREE3.0 Materials and Methods3.1 Description of the Studies AreasKaolin samples were collected from two different locations namely: kpankorogi and ijero Ekiti.Kpankorogi in Edu local government area of Kwara State is located in northern part of Kwara state on latitude 08052’38-6’’N and longitude 04059’55.5’’E at 72KM distance from Ilorin, the state capital. The Kpankorogi ar ... Continue reading---
CHAPTER FOUR - [ Total Page(s): 5 ]The result of the oxide analysis is presented in the table 4.3. Elemental oxides found in the Samples are SiO2, Al2O3, Fe2O3, TiO2, MnO, CaO, MgO, K2O, Na2O, CuO, ZnO, Cr2O5, V2O5 and Se2O3, Table 4.5 shows the requirement and industrial specification. SiO2 of both Samples can be used in refractory bricks, ceramics, Al¬2O3 meets the requirement for refractory bricks, ceramics, and coating, TiO2 meets the range and can be used in refractory bricks, rubber, ceramics, and bricks clay, CaO meet ...
